Abstract (en)

The invention relates to a method for the processing and transport of hexane-1,6-diamine or pentane-1,5-diamine comprising the steps of:a) Providing a first composition including 60 to 98 wt.-% water and 2 to 40 wt.-% hexane-1,6-diamine or pentane-1,5-diamine,b) partially removing water from the first composition by distillation at a first production location, whereby a second composition is generated, said second composition including the hexane-1,6-diamine or pentane-1,5-diamine and 0.5 wt.-% to 55 wt.-% water, andc) transporting said second composition during a span of time t from the first production location to a second production location, wherein the span of time t including times for optional temporary storage is at least 6 h.
